Dyspepsia is a common, benign condition that may be distinguished from gastroesophageal reflux, irritable bowel syndrome and pancreatobiliary, coronary or musculoskeletal disease by a careful history and physical examination. However, the presence or absence of a peptic ulcer in dyspepsia can be determined only by an endoscopic examination or a barium-contrast radiograph. Although the American College of Physicians has recommended trying drug therapy for patients with dyspepsia before diagnostic tests are done, new data support early diagnosis. Although therapy is initially cheaper than endoscopic examination, over a year the costs even out because most patients with dyspepsia eventually need an endoscopic examination, and many patients with nonulcer dyspepsia are given medication unnecessarily. Endoscopic examination, if available to general practitioners, is the most cost-effective approach to dyspepsia. An approach that does not include endoscopy lacks the opportunity to offer patients convincing reassurance that their illness is not serious, which is arguably the most important treatment in cases of nonulcer dyspepsia. Studies supporting the use of endoscopic examination predate the treatment of peptic ulcers with antibiotics, which makes an initial endoscopic examination to determine whether the patient has an ulcer even more important.
消化不良是一种常见的良性病症,通过详细的病史询问和体格检查,可将其与胃食管反流、肠易激综合征以及胰腺、胆道、冠状动脉或肌肉骨骼疾病相鉴别。然而,消化不良患者是否存在消化性溃疡只能通过内镜检查或钡剂造影来确定。尽管美国医师学会建议在进行诊断性检查之前先对消化不良患者进行药物治疗,但新的数据支持早期诊断。虽然药物治疗初期比内镜检查便宜,但一年下来费用会趋于平衡,因为大多数消化不良患者最终都需要进行内镜检查,而且许多非溃疡性消化不良患者被不必要地给予了药物治疗。如果全科医生能够开展内镜检查,那么这是诊断消化不良最具成本效益的方法。一种不包括内镜检查的方法无法让患者确信其病情并不严重,而这可以说是非溃疡性消化不良病例中最重要的治疗手段。支持使用内镜检查的研究早于用抗生素治疗消化性溃疡,这使得进行初步内镜检查以确定患者是否患有溃疡变得更加重要。
